18758-54-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18758-54-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,5 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18758-54:
(7*1)+(6*8)+(5*7)+(4*5)+(3*8)+(2*5)+(1*4)=148
148 % 10 = 8
So 18758-54-8 is a valid CAS Registry Number.

Exploring Multistep Continuous-Flow Hydrosilylation Reactions Catalyzed by Tris(pentafluorophenyl)borane

Wilkins, Lewis C.,Howard, Joseph L.,Burger, Stefan,Frentzel-Beyme, Louis,Browne, Duncan L.,Melen, Rebecca L.

supporting information, p. 2580 - 2584 (2017/08/16)

Exploring the combination of continuous-flow processes with the boron Lewis acid catalyzed hydrosilylation of aldehydes and ketones has delivered a robust and generally applicable reaction protocol. Notably this approach permits ready access to high temperatures and pressures and thus allows improved reactivity of substrates that were previously recalcitrant under the traditional approach. Efforts to quench the output from the flow reactor with water showed surprising tolerance leading to the application of continuous-flow systems in multistep imine formation/hydrosilylation processes to generate the corresponding secondary amines from their aldehyde and aniline precursors. (Figure presented.).
